kernel: drm/amdkfd: validate SVM ioctl nattr against buffer size
A flaw was found in the Linux kernel. A local attacker could exploit an out-of-bounds buffer access vulnerability in the AMDGPU kernel driver by providing a specially crafted attribute count during SVM ioctl operations. This improper validation could allow the attacker to cause a system crash, leading to a denial of service (DoS).
